4. In some cases, it may be necessary to drive
the vehicle for several minutes at a speed of
at least 20 mph (30 km/h) to erase the
TPMS telltale warning and the text message.
Please be aware that the TPMS telltale
warning will not go out until the low tire pres-
sure has been corrected and calibration has
been carried out.
NOTE
To help avoid incorrect tire inflation pressure,
if possible only inflate the tires when they are
cold. The tires are considered to be cold
when they have the same temperature as the
surrounding (ambient) air. This temperature is
normally reached after the vehicle has been
parked for at least 3 hours. After driving a dis-
tance of approximately 1 mile (1.6 km), the
tires are considered to be warm.
CAUTION
When inflating tires, press the pump's mouth-
piece straight onto the valve to help avoid
bending or otherwise damaging the valve.
CAUTION
•
After inflating the tires, always reinstall
the valve cap to help avoid damage to the
valve from dirt, gravel, etc.
•
Use plastic valve caps only. Metal caps
could corrode and become difficult to
remove.
WARNING
•
Incorrect inflation pressure could lead to
tire failure, resulting in a loss of control of
the vehicle.
•
Tire monitoring systems cannot indicate
sudden tire damage caused by external
factors (e.g., a blowout) in advance.

Calibrating the Tire Pressure
Monitoring System (TPMS)
In order for the Tire Pressure Monitoring System
to work properly, tire pressure reference values
must be set correctly. This must be done each
time wheels are changed or tire pressures are
modified.
Calibrating TPMS
To calibrate the system:
1. Switch off the engine.
2. Re-inflate the tire(s) to the correct pressure.
Consult the tire pressure decal located on
the driver's side B-pillar (the structural mem-
ber at the side of the vehicle, at the rear of
the driver's door opening) or the inflation
pressure table in your printed owner's man-
ual supplement.
3. Start the engine.
4. Open the
Car status
app in the center dis-
play's App view.
5. Tap
